To all who/m 'it may concern."

Be it known that I, ALEXANDER Dow, a citizen of the United States, residing at New York, in the count-y of New York and State of New York, have invented certain new and useful Improvements in Means for Locking Detachable Flanges on Deniountable Rims, of which thefollowing is a" specification. r

My inventiony relatesl to means for locking detachable flanges on deinonntable rims, whereby theflanges are prevented from becoiningloose Aon the rim, flying of and releasing the tire secured thereby.

My invention is applicable to substantially any of the well knowln types of detachable flange whenapplied to a de1nount-v able rim. i A

l/Vhile iny invention may be used in connection with substantially any detachable flange, il have showi'i the saine, in order to illustrate my invention, when used in con nection with what is known as the Standard universal quick detachable rim, in which the detachable fiange is retained in'position by a split ring which contracts around the riin oi' the wheel to secure the detachable flange onto the rim.

The forni ot' have illustrated is that known as the l"ii'c stone deinonntahle rim.. in which the under side of the",demonntable r'nn is provided with oppoeitely arranged 'wedge surfaces,

and there is provided a corresponding wedge surface on the tixed portion ot the rnn with which one ot the wedge snrtaces on the deinonntnblc riin contacts, nndthere is also provided a. ring having a wedge shaped side adapted-to contact with the otherwedge surface of the deinountable rini. llateeQa-re need to secure the wedge ring in position, the plates being secured to the fixed rim by suitable securing means, 4

such as bolts. .it is evident, however, that the use of my invention is not to be lim` ited to the 'torni et' denionntable flanges or to the foi-in of deniountable rims herein shown and described, but iny invention may be applied to any well known or desired riin to which it may be found applicable.

My invention consists 'in certain constructions, coinbinatioi'is and arrangements of parte, one torni ot which deinoniitablc i'ini which l' the hook ends willmbe first describedin connection with the accompanying drawings and then the invention particnlarly pointed out in the appended claims.

Referring to the drawings wherein the same part is designated by the same reference numeral wherever it occurs, Figure 1 is a side elevation of a wheel provided with an embodiment of my invention; Fig. 2 is a detailed side view of the locking means for the ends of the split-retaini1ig ring, the saine being shown on a larger scale than Fig. 1; Fig. 3 is a section taken on line 3, 3 ot' Figs. 65 1 and 2 and Fig. t is a section taken on line 4, 4: of Fig. 1. y

5 designates a felly which is shown as` having attached thereto a felly band 6, one side of which is forinedinto an upwardly turned flange 7 which forms a wedge. The side of the felly band 6 opposite that carrying' the wedge 7 is beveled ott', as shown-at 8, to` forni a bearing for one side of the wedge, shaped locking ring 9.

10 is a deinonntable riin to the under side of' which are secured the plates 11, having their opposite edges beveled off to engage with the incline sides 7 and the upper edfre of the retailing ring 9. The ring S) is held in position by means of a series ot' plates 12 which are secured to the fixed riin by menne ol the bolts 13. I

The construction so far described forms no part of my invention, asit is what is known in the trade as the Firestone demountable riin, and is merely shown as illus- ,trating one form of demountable rim to which niy inventioiimay be applied.

The rini 10 is shown as turned upat one 90 side to forni a permanent tire retaining flange 14, and on the opposite side of the rim a depression or channel 15 is formed having` an opening 16 at one portion of the circun'ii'erence of the rim. j 95 17 is a retainingring which' issplit. and has its ends formed in the inwardly projecting hooks 18. 4 l A `l 19 is a detachable tire-retaining flange which slips over the edge ofthe riinand isv held in place by the retaining ring 17, which fits into the channel 15 with the hook ends 18 of the ring extending through the openings 16. Except for the opening 16 and the well knownStandard universal quick de'- 18 tliecoiistruction is that of 105 -ielly in the ends 1S will possible in the details taehable' rim, and forms-no part of my invention. In order to lock these retaining liange'sin position and also prevent the ringv from becomingr accidentally detached I provide thet'elly with an opening which is adapted to he engaged by the hooks onl the ends of the retaining ring when the rim is placed on thexielly so as to lock the ends of theA ring. shown this is effected by providing the felly 5 with a plate 23 secured to the fellyby means of the screws 20, said plate beingr provided with the boss 21 havingr the oblong slot or opening 22 veut therein. Vhen the demounta'ble rim is placed in position on the ordinary manner and pushed transversely enter the opening 22, whereby the ends of the split ring will be locked on to the rim.v The ring can only be Aremoved after the rim has been demounted.

I realize thateonsiderable variation I is of construction and arrangement of parts Without departing from the spirit of my invention, and I therefore Vdo not intend to limit myself to the specific form shown and described.

Havingl thus described my invention what I claim as new and desire to secure by Let` ters Patent is: y

1. Ina wheel, a fixed member, a demonntable rim therefor, means to secure the rim to the fixed member, a split ring on the rim, and locking means on the end portions only of the split ring and on ythe fixed member adapted to be brought into locking engagd ment when the rim is slipped by a transverse In the form of my invention of the felly to its seat the hook' nemici movement only fixed member.

9. In a Wheel, a ixed member, a demountable rim therefor, means ',to secure the rim t0 ther'xed member, a' split ring on the rim, and means for locking the ends of the split ring to the -ixed member, comprisingan opening formed in onepart, and a projectingportion carried by the other part which are adaptedto be brought into lockinfr engagement when the rim is 'slipped y a transverse movement only to its proper position on the fixed' member.

In a wheel, a fixed member, a demountable rim therefor, means to secure the rim to the fixed member, a split ring on the rim, a hook formed on one end of the ring, the fixed member beingprovided'with an opening' with which'the hook engages when the rim is secured ou the fixed member and means for locking the other end of the ring in position.

Il. In a wheel, a fixed member, a demountable rim therefor, means to secure the rim to the fixed member, a split ring on the rim, an inwardly projecting hook formed. on each end of the ring, the fixed member being provided with 'an opening with which the hooks engage when the riln is secured on the xed member.

ln testimony whereof I ailix my signature in presence ol two witnesses.
